Tyrrellite

James Burr Tyrrell
Formula:
Cu(Co3+,Ni3+)2Se4
System:
Isometric
Colour:
Bronze
Hardness:
Name:
Named in 1959 by Nina Dmitrievna Sindeeva in honor of Joseph Burr Tyrrell (November 1, 1858 Weston, Ontario, Canada - August 26, 1957), geologist, Geological Survey of Canada.

Robinson & Brooker (1952) gave a partial description of an unnamed selenide from Ato Bay (TL2), which according to Harris (1970) was later informally named tyrrellite by Robinson. The name appeared in Hey (1963) and elsewhere without explanation. It was properly confirmed as a new species by Harris (1970), who completed the full description of the mineral on material from Eagle claims (TL1) (Horváth 2003).
